RING TRAVELER.

Application flied February 16, 1926. Serial No. 88,544.

This invention relates to improvements in ring travelels for twisting machinery. It .has for its object a traveler which, as compared with. prior devices, will produce a more uniform quality of yarn both as to size and degree of twist and will enable the traveler to, be run continuously for longer periods of time with less frequent lubrication. These results are accomplished by improving the lubricating qualities of the traveler as I will-"particularly point out below.

Referring to the drawings Fig. 1 is a perspective view showing the improved traveler in the position it assumes in actual use;

Fig. 2 is .a perspective view showing the traveler by itself; and Fig. 3 is a sectional 33 of Fig. 2.

Twisting machinery consists generally in a driven spindle 10 located centrally within a twister ring 11. Mounted on the ring, as clearly shown in Fig. 1, is the traveler 12 which is bent around the ring to hold itself in place. As the spindle rotates, the yarn 13 which is looped under the upper side of view taken on line the traveler causes the latter to travel. with.

extreme rapidity about the ring in the di rection shown by the arrow 14.

Variations in'the friction which the traveler has upon the ring will cause a variation in the tension imposed upon the yarn with a consequent variation in size and twist given to the latter. It is necessary to lubricate the inner surface of the twister ring very frequently, generally at every do and sometimes more often.- If too long a period is allowed to elapse between lubricating, it

is found that the frictionof the traveler on the ring will vary to such an extent that the yarn is not uniform in quality.

Referring in particular to Fig. 3, my invention resides in providing the leading edge of the traveler with a recess '15, preferably extending the whole length of that part of the traveler which is adjacent the inner surface of the ring. When the twister is started after the ring has been lubricated, this recess immediately fills itself with grease which it picks up from the inner surface of the ring. In further operation of the twister this recess gives upits grease as the traveler becomes warm through the friction of its motion. This continuous lubrication keeps the traveler in proper condition for a much longer period than is possible with the old style travelers. Furthermore, the continuous lubrication keeps the traveler at all times under uniform friction 1. A ring traveler having a lubricant receiving recess opening into the leading edge of the traveler.

2. A ring traveler having alubricant receiving recess extending the full length of the traveler.

3. A ring traveler having a lubricant receiving recess located at the leading edge of the traveler and extending substantially throughout its length.
